Configuring multihomed hosts in a datazone

The following table summarizes how to configure the NetWorker environment to use a multihomed NetWorker server, storage node, and client.

Table 1. Configuring multihomed hosts in NetWorker (continued)
Multihomed host	Required behavior	NetWorker configuration requirements
NetWorker server	The client sends metadata to the NetWorker server by using a specific NetWorker server NIC. The metadata includes the save set control session information and index database operations.	The servers file on each client must contain the shortname and FQDN for each NetWorker server NIC. The Server network interface attribute of each Client resource must contain the FQDN of the NetWorker server NIC. Each instance of the Client resource must have the same value for the Server NetWorker Interface attribute. The Alias field for the NetWorker server Client resource must contain an entry for the shortname and FQDN of each NIC.
	Each storage node device sends metadata to the NetWorker server by using a specific NetWorker server NIC. Metadata includes the device control session information and the media database operations that connect back to the nsrmmdbd process on the NetWorker server.	The Server network interface attribute of each Storage Node resource must contain the FQDN of the NetWorker server NIC. The Aliases attribute of the NetWorker server Client resource must contain an entry for the shortname and FQDN of each NIC.
	Each storage node library sends metadata to the NetWorker server by using a specific NIC on the NetWorker server. The metadata includes SCSI commands for the tape movements and the library inventory operations that connect back to nsrmmgd process.	The Server network interface attribute of Library resource must contain the FQDN of the NetWorker server NIC. The Aliases attribute of the NetWorker server Client resource must contain an entry for the shortname and FQDN of each NIC.
Storage node	The client sends backup data to a NetWorker storage node over a specific NIC.	The Storage Nodes attribute of each Client resource must contain the FQDN of the storage node NIC. This also applies when the NetWorker server is the storage node. The Aliases attribute in the Client resource for the storage node must contain an entry for the shortname and FQDN of each NIC.
Client	The NetWorker server communicates with a client over a specific NIC.	When you create a Client instance for the client, specify a hostname for the client that is only reachable over the desired NIC.
